The Zollverein or German Customs Union was forme among the majority of the states of the German Confederation in 1834 during the Industrial Revolution to remove internal customs barriers, although upholding a protectionist tariff system with foreign trade partners. The main ideological contributor behind the customs union was Friedrich List, an economist holding mercantilist and protectionist views. The Zollverein totally excluded Austria because of its highly protected industry; this economic exclusion would later exacerbate the Austro-Prussian rivalry for dominance in central Europe during the late 19th century. The Zollverein was effectively ended in 1866 with outbreak of the Austro-Prussian War; a new organization with the same name was brought about in 1867 when peace was restored. The new Zollverein was stronger, in that no individual state had a veto.
